Mr. mm came across this guy’s filters while doing a project for work. They had the water tested that ran through them and they work very well so we got one for our home.
They are effective and MUCH cheaper than most out there, especially the counter top , pyramid scheme distributors, who often charge hundreds or thousands of dollars for theirs.

If you’ve heard of big berkey filters, the design was copied from “Berkefeld” which was invented by the people at the link above.
We used a pair of cheap ceramic filters from cheaperthandirt for a year and drank water from a spring fed stream without issues. They no longer carry them. We used the two bucket, gravity feed system. It’s all a matter of micron rating. Also, there are a few ceramic filters that are approved by the NSF.
